A multimedia collaboration home study system offers real time multimedia distance education system environment by home PCs and network environment. It supports real or non-real type. Also, it does not restrict on space among teachers and students into cyber-space made by network. Networks are PSTN, LAN, MAN, and WAN. It has an interaction, various communication types, a question and an answer, multi-session, application sharing, high degree of efficiency, high degree of cooperative. After a conventional method detects an error, it detects and classifies an error type by polling periodically all the process. But it is not efficient method. Therefore, the main idea of proposed method is to detect an error type by polling only process with relation to session manager. This paper explains a performance analysis of an error sharing system running on multimedia collaboration home study system using the rule-based SES(System Entity Structure) and DEVS(Discrete Event System Specification) modeling and simulation techniques. In DEVS, a system has a time base, inputs, states, outputs, and functions.
